There's a large pit with three spinning platforms hovering over the pit.
If you don't want to wait for the shaman, rushing is a somewhat safe strategy. Just watch out for the rotation of the platforms! Use it to get sliding momentum to get ahead of the other mice.
Pros can walljump up if they fall on the last platform.
If you are fast enough, summon two planks, with the edges standing on two of the spinning platforms, preventing the rushing mice to start rotating them. Be careful, do not rotate the platforms while doing this!
